You can mange this using saveInto on the submit button. 
 a!formLayout(
 label: "Form",
 contents: {
 a!dateField(
 label: "Date",
 labelPosition: "ABOVE",
 value: ri!theDate,
 saveInto: ri!theDate,
 validations: {}
 )
 },
 buttons: a!buttonLayout(
 primaryButtons: {
 a!buttonWidget(
 label: "Submit",
 saveInto:{
 a!save(ri!theDate,if(isNull(ri!theDate),fn!today(), ri!theDate))
 },
 submit: true,
 style: "PRIMARY"
 )
 },
 secondaryButtons: {}
 )
)

It also seems you want to default to today's date as well. 
 I will add on to Bob's answer with the following code. Note the updated "value" field for the dateField. 
 {
 a!dateField(
 label: "Order Submission Date",
 value: if(
 isnull(ri!OrderSubmissionDate),
 fn!today(),
 ri!OrderSubmissionDate
 ),
 saveInto: ri!OrderSubmissionDate,
 required: true
 ),
 a!buttonLayout(
 primaryButtons: {
 a!buttonWidget(
 label: "Submit",
 saveInto: {
 a!save(
 ri!OrderSubmissionDate,
 if(
 isnull(ri!OrderSubmissionDate),
 fn!today(),
 ri!OrderSubmissionDate
 )
 )
 },
 submit: true
 )
 }
 )
}
